Your error is nothing like what was being discussed in this thread. Changing subject for you :)
What target are you using?
What version of open-iscsi? What kernel what userspace tools?
When you see this, what is in the target's logs?
How are you discovering another LUN? What command are you running?

The target did not like something we did. It is reporting a protocol error.
We have never seen this error before. The initiator just logs the error and does nothing.

Target stopped responding to us.

We dropped the connection. The scsi eh eventually runs and we cannot recover the device.
